This is not possible unless you're using a TrueColor X-windows device.
I'm not sure if MPE allows changing your colormap (or even using a non-shared
one!).  If so, this will give you 256 colors.  As an alternative, you may
add colors to the shared colormap (again around 256 colors), by requesting
colors such as "red".  I'm not sure if MPE allows this either, check out the
manpages.
